A novel system for detecting inefficiencies in a refrigeration circuit, such as an air conditioner system, is disclosed whereby a sensor sends a signal to a controller which will cause the compressor of the refrigeration circuit to be shut off when the evaporator is at risk of freezing out. The shutdown system of the present invention provides for controls that maintain the compressor in the shutdown condition allowing the evaporator a chance to recover, after which, the shutdown system will restore power to the compressor and will allow the operation of the refrigeration circuit to re-commence without experiencing a loss of efficiency that would occur if the refrigeration circuit continued to operate with a frozen evaporator for extended periods of time.
